What Huo Xue Zhi Tong San is for
This is a short, strong powder for skin that has been bruised or injured and has gone dark, hard and sore. Strong Blood-moving substances break the stasis that has set in the tissue, an aromatic relieves the pain quickly, and the powder is taken for a few days rather than a few weeks. It is built for recent injury, where the tissue is still settling and the discolouration is still fresh.
After an injury the skin over the area turns dusky purple or blue-black, swells, and feels hard and tender to press. The discolouration is the Blood that has left the vessels and is sitting in the tissue, so the colour is fixed and does not fade with warmth the way a light bruise does. The pain stays in one place and sharpens on pressure. The surface stays intact, with no break, no ulcer and no spreading redness, because this is stasis in the tissue rather than infection.
Dang Gui is the base, nourishing and moving the Blood so the tissue has something to repair with, and Tu Bie Chong, a strong stasis-breaking insect, reaches the fixed congestion that ordinary movers cannot shift. Zi Ran Tong, San Qi and Ru Xiang move the Blood and relieve the pain from different angles, and a very small amount of Bing Pian gives fast aromatic relief on contact. The proportions matter: the powder is built for a few days of acute clearing rather than for long-term use.
The formula belongs to recent injury, where the tissue is still settling. Old, dried stasis that has been present for months needs a different approach, and any injury with deformity, severe swelling or inability to bear weight needs medical assessment before treatment. It is contraindicated in pregnancy because it moves the Blood strongly, and the powder is not applied to broken skin.

The pattern behind it
The pattern is Blood stasis from injury. The extravasated Blood congests the tissue, producing swelling, bruising and fixed pain, and the congestion prevents healing. The formula breaks the stasis and moves the Blood so the tissue can recover.

Patterns it treats
Blood Stagnation
Dusky purple or blue-black skin over an injured area, swollen and hard, with pain that stays in one place and sharpens on pressure. The colour is Blood that has left the vessels and settled in the tissue, which is why it does not fade with warmth.
How the formula is built
The powder is built around Dang Gui with a smaller amount of a strong stasis-breaking insect, supported by three pain-relieving herbs and a small aromatic. The proportions matter: the formula is short and pain-focused rather than a broad tonic.
